Anthropic says its life sciences team used Claude to search large DNA datasets, leading to an early laboratory-validated finding after roughly 21 hours of work by about 950 agents. The previously uncharacterized system, called array-associated reverse transcriptases (ART), is found mainly in bacteriophages and combines a reverse transcriptase, a neighboring partner gene, and a long array of DNA repeats reminiscent of CRISPR. Its primary function remains under investigation, so the post describes an early research result rather than a finished biomedical application.
